Decorator in Python

Decorator in Python
Import in Python
In Python, decorators are functions that can
modify or enhance the behavior of other functions without changing their source code. They're often used to extend functions, classes, or methods, and promote reusability and modularity.
How they work:
A decorator function takes another function as an argument.
The decorator modifies the accepted function and returns the modified version.
When the decorated function is called, the result may have extra features compared to the original definition.
Benefits:
Extend functionality
Decorators can add new functionality to existing objects without changing their structure.
Clean logic:
Decorators can be used for logging, like printing transaction details before and after the function runs, without adding code to the core function.
Improved debuggability:
Logging messages can be sent to a monitoring dashboard or analytics system for better tracking and observability.
Decorators in Python
Decorators are a very powerful and useful tool in Python since it allows programmers to modify the behaviour of a function or class. Decorators allow us to wrap another function in order to extend the behaviour of the wrapped function, without permanently modifying it. But before diving deep into decorators let us understand some concepts that will come in handy in learning the decorators.
